Astronomers at the European Southern Observatory (ESO) have identified the biggest quasar outflow, a type of high energy explosion. Gammablitz: Explosion am Rand des Universums beobachtet Den Distanzrekord hält ein kürzlich entdeckter Quasar. Quasare enthalten die. Stellar black holes, which are around the mass of our Sun, form when very large stars explode as supernovae at the end of their lives. The star's core collapses. The luminosity of some quasars changes rapidly in the optical range and even more rapidly in the X-ray range. This spectrum revealed the same strange emission lines. That ejection of matter could answer an important question about the universe: Quasars may also be ignited or re-ignited when normal galaxies merge and the black hole is infused with a fresh source of matter. The scientists will of course keep an eye on this quasar, performing observations in different wavebands. When viewed downward, these appear as blazars and often have regions that seem to move away from the center faster than the speed of light superluminal expansion. According to fire officials, no one was injured and there was no immediate threat to public safety. Wie das geschehen konnte, wissen die Forscher noch nicht. Several dozen nearby large galaxies, with no sign of a quasar nucleus, have been shown to contain a similar central black hole in their nuclei, so it is thought that all large galaxies have one, but only a small fraction are active with enough accretion to power radiation and so are seen as quasars. How do you account for quasars? Schwarze Löcher oder Sternenhaufen? Micro Extremal Electron Stellar Intermediate-mass Supermassive Quasar Active galactic nucleus Blazar Large quasar group. Die Wellenfront in etwa The matter accreting onto the black hole is unlikely to fall directly in, but will have some angular momentum around the black hole that will cause the matter to collect into an accretion disc.
